I have a tag change script which works and logs fine as a Client Event Script, but when I run it as a Gateway Event Script, I can’t find the log messages even though I can functionally see that my script is running.
Are you seeing any error logs where the script should be? What is the full script you are running? Make sure you are doing import system.util. I think it’s necessary for gateway scripts to import which is not always the case with certain client contexts iirc.
I've gotta talk someone who has access to that machine into looking at this for me... what do I ask for other than just modified dates on the files? Should they delete them? Is there another way they can reset them?
Wherever Ignition is installed there should be a logs directory with a system_logs.idb file in it. I’d ask them to stop the Ignition service, move this file somewhere else (or delete it if you don’t care about the old logs), then start Ignition again. It should create a new one and hopefully your diagnostic logs in the gateway will be current again.
